PRINTING-PRESS MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 276,621, dated May 1, 1883. Application filed September 2, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, CHARLES F. OWEN, of Chicago, .county of Cook, State of Illinois, haveinvented a new and useful Improvement in Printing-Press Movements; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form a part ofthis specification.

My invention consists in the combinations of devices and appliances hereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figurel is an inverted plan view of an apparatus embodying myinvention. Fig. 2 is a side elevation of the same, showing parts in section. Fig. 3 is a separate view of the stanwheel shown at the end of the rack. Fig. 4 represents separate views of the end pins.

The object of my invention is to provide a bed and cylinder movement for printingpresses in which the bed is constructed with a rack in which a star-wheel located upon a swiugingframe meshes,the star-wheel being operated' by the driving-gear in such a manner that the bed is propelled to and fro, as desired.

In carrying out my invention, A is a suitable pedestal or arm secured to the frame of the press.

B is the drive gear-wheel.

The shaft 1), which carries the drive gearwheel B, is driven by the driving-shaft of the press by suitable gearing.

O is the bed-plate.

0 represents a rack secured to the bed-plate or bed. The device admits of the simplest and most inexpensive form of rack. It may be made, for instance, by inserting a row of steel or iron pins, 0 into the bottom of the bed itself perpendicularly, or be otherwise constructed. V

D is a swinging frame, properly secured upon the shaft 1). E is a pinion secured to the swinging frame by the shaft 6, in such a position that it is adapted to mesh with the drive gear-wheelB. F is a star-wheel secured upon the shaft 6, and adapted to mesh with the rack c, secured to the bed of the press. This mechanism is preferably so located that the planes of the gear-wheels and the swinging frame are horizontal. By this means the motion is ap-. plied to the bed very near to its surface, thus obviating the tendency of the bed to tip up at the end of itsjourney when it butts the huntersprings. I prefer to unite the two outer pins 0 by a suitable connecting-clasp, c, to give greater strength to the end pin, as it is evident that peculiar strain comes upon it. I also prefer to provide the end pin with a friction-ferrule, 0 with a guide, f, to engage against the curved end 0 of the bed when the star-wheel reaches the end of the rack, and cause the swinging frame D to swing over to the other side of the rack, as shown in Fig. 1 by the dotted lines.

In the practical operation of the device there should be a lug or stop on each side of the rack to prevent the swinging frame, with its star-wheel, from swinging too far and getting out of gear when it goes by the end of the rack. This stop may have any suitable location.

The operation of the device will now be understood. The drive gear-wheel B, propelled by the driving-shaft b, meshes with the pinion E, whereby the star-wheel is rotated, and this, meshing with the rack 0, causes a movement of the bed-plate (J. When the star-wheel reaches the end of the rack it is guided by the guide f, working in the curved end 0 ofthe bedplate, around on the other side of the rack, as shown by the dotted lines in Fig.1, pro duciug again the required movement of the bed. It is evident that this form of movement admits of the gear-wheel 13 having a very great range in :diameter. I prefer that the guidef should be provided with a friction-ferrule.

\Vhat I claim is- 1. A movement for printing-presses, consisting of the combination, with the bed provided with a rack, of a driving gear-wheel adapted to be driven by a shaft, the swinging frame I), hung upon said shaft, a pinion secured by shaftingto said swinging frame, adapted to mesh with the driving gear-wheel, and a wheel driven by said pinion, adapted to mesh with said rack, substantially as described.

2. A movement for printing-presses, consisting of the combination, with the bed provided with a rack, of a driving-wheel adapted to be driven by a shaft, the swinging frame D, hung upon said shaft, a pinion secured by shafting The star-wheel F is provided to said swinging frame, adapted to meshwith I 4. In a printing-press, a bed provided with the driving gear-wheel, and a wheel driven by a rack constructed of pins secured to said bed,

said pinion, adapted to mesh with said rack, said wheel provided with a guide, substantially as described.

3. Thecombination,inaprinting-presslnovement, of a bed provided with a rack, a driv- I ing-wheel adapted to be driven by a shaft, a pinion carried by the swinging frame, and adapted to engage the driving gear-wheel, and a wheel adapted to engage the rack, and provided with a guide,substantially as described.

the outer pins provided with a connectingr 5 clasp, and the end pin with a friction-ferrule, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
